Analysis

While it was not possible to determine the controller’s level of fatigue, it is likely that the significant level of workload and the controller’s acknowledged diminished level of mental alertness and the time of day, together contributed to the incident.

The routine display of CLAM alerts for expected events, such as the issue of discretionary climb, did little to enhance the controller’s situational awareness in regard to QF31s cleared level status.
